An ore is as different from the metal, as a piece of rust is from iron, elemental sodium from rock salt, or hydrogen and oxygen gas from water. Smelting means to break that chemical compound apart into the pure metal and some residue; chemically this is called reducing the ore. Smelting water, for example, would mean to break it apart into
